A beginner connected a PCIe cable into an EVGA 1000W power supply, but power isn't coming out anymore.
I'm completely new to PC building and didn't realize how complicated it could be. Please don't criticize me or make me laugh—I already feel the worry of losing hundreds of dollars. I was trying to get my GPU working because it needed more power than what was available from the cords I got from the previous owner's case and PSU. After delaying, I bought a PCIe cable to provide the extra power needed. It finally arrived today (I've had my PC for weeks now) and I was searching for a place to connect it. Unfortunately, it didn't fit in the VGA slots physically. Maybe this is obvious, but I haven't even touched any of these parts before. I plugged it into the CPU 2 slot without thinking, turned on the PC, and got nothing. I re-seated everything on the motherboard and reconnected all power connections, but still nothing happened. I suspect the PSU might have been damaged, possibly shorting out other components too. There were no visible signs of damage, but the rest of the system seems fine except for a faint light that used to work but now isn't. My concern is whether the EVGA PSU can still function and if I need to replace it entirely, or maybe just my CPU. To be honest, I'm 18 and paid for everything myself with some help from gifts. I really hope I don’t have to spend more, especially since I returned a couple of PSUs I accidentally ordered, not realizing I already had one in the case. I returned them because I found another model on sale elsewhere, then had to send both back.
You asked about the exact item you bought. Did you receive a link to the product or are you referring to a PCIe PSU cable? I’m trying to understand your question better. You mentioned ordering a CPU cable for a specific PSU? Did you connect it to your video card power connector? The main concern might be that the cable was for a different PSU model, possibly with varying power and ground connections on the PSU side. Also, some power supplies have identical connectors on both sides, so using a CPU cable could still work. I can’t confirm definitively what happened, but it’s possible the PSU or your graphics card had the cable as well. Let me know if that makes sense.
Whoops, I had the wrong PCIe power supply, it was a cable instead. The PSU is an EVGA Supernova 1000 P2 80+ Platinum. The motherboard is a Gigabyte B660M DS3H DDR4 Micro ATX LGA1700 board. And the CPU is an Intel 12600K.
It seems you're reflecting on a purchase that didn't meet expectations. You noticed it was labeled as Corsair but realized later it wasn't what you thought it was, leading to disappointment and financial loss.
You mentioned several points about testing a Corsair power supply. The details seem mostly accurate. The 24-pin cable’s pinout is consistent across manufacturers, which helps with compatibility. Plugging the Corsair cable into the motherboard’s CPU2 port and checking for power, fans, and RGB lights confirms the issue. If the power supply has a 0db mode, it won’t spin unless it gets hot, so testing a compatible fan controller can verify functionality. Modern hardware includes safety features, reducing the chance of damage.
